Preliminary ABMX0127
www.D2ata7SMheeHt4Uz.coXm O IC with Audio Clock (for Set Top Boxes & MPEG Video)
FEATURES
• 27MHz reference output (from 27MHz crystal
input or clock input).
• Selectable Audio Clocks supporting:
Fs of 32kHz, 44.1kHz, 48kHz, 64kHz and 96kHz
8.192MHz, 11.2896MHz, 12.288MHz, and
24.576MHz audio frequencies
• On-the-fly switching of the audio frequency.
• 3.3V Operating Voltage.
• Available in 8-Pin SOIC.
DESCRIPTION
The ABMX0127 is a low cost integrated XO IC
designed to work with a fundamental 27MHz crystal
or a clock input. In addition to a 27MHz clock
reference, it provides the most common audio clocks
(8.192, 11.2896, 12.288, and 24.576MHz) required by
sampling rates of 32kHz, 44.1kHz, 48kHz, 64kHz and
96kHz, making the chip ideal for STB and MPEG
Video applications.
